I was contacted by Nations Recovery Center in - - in regard to a debt that was charged off in -. - - called saying that he was collecting this debt and that I need to pay the entire debt of $7400.00. I requested supporting documentation to prove his firms right to collect the debt. 2 weeks passed and after my receipt of supporting documents to prove he had any right to collect the debt, he again contacted me. We had come to a verbal agreement of $3200.00 and he was to email me a settlement letter to sign with that amount. 2 weeks passed and instead of receiving the settlement letter from - -, I receive an emailed settlement letter from - - and a - - CC'ed. It 's for $5200.00 I feel the false statements by all parties named has caused a real problem. I am not sure who to believe or whether this is a real company. They may have the same dotcom but all contacts have different phone numbers and none seem to know what either is doing.
